  • Dell HT953 part number ensures compatibility

Dell HT953 300GB SAS drive

The Dell HT953 is a 300GB internal hard drive with a SAS interface and a 15K rotational speed. It uses a 3.5 inch form factor designed for desktop and server drive bays. The drive carries the Dell part number HT953 and the manufacturer model ST3300655SS. It is supplied in new condition.

Suited for SAS arrays needing 300GB 15K spindles

This drive fits systems that accept 3.5 inch SAS drives and require 15K performance at the 300GB capacity point. It is not for builds that need larger capacities or the SATA interface. Buyers who want higher storage density or a different interface should look at other options.

15K SAS rotational speed

The 15K spindle speed is the specification that determines whether this drive meets the performance profile for transaction-heavy workloads. Verify that your controller and backplane support SAS at this speed before purchase. The 300GB capacity and 3.5 inch form factor are the other fixed attributes.

Highlights

  • 15K spindle speed accelerates data access
  • 300 GB capacity stores critical workloads
  • SAS interface enables dual-port reliability
  • 5 inch form factor fits standard bays
  • Dell HT953 part number ensures compatibility

Questions about this item

What does the 15K RPM rating mean for real-world throughput on this drive?

The 15K spindle speed gives lower latency and higher sustained transfer rates than slower enterprise drives, so random I/O and sequential reads stay responsive under heavy workloads.

How does the SAS interface limit actual transfer speed in a typical server?

The SAS connection negotiates its link speed with the controller; the drive itself is rated for the SAS standard, so real throughput caps at whatever the host bus adapter supports.

Will this 3.5 inch SAS drive fit in a standard 3.5 inch drive bay?

Yes, the 3.5 inch form factor matches standard 3.5 inch bays and the SAS connector aligns with typical backplane or cabled installations.
